You don't Need the kicker amp, you could go with another amp that puts out the correct rms watts at the correct ohm rating. As long as it's a good quality amp from a good quality brand you should be just fine. How much have you found the kicker amp for?

Try checking out audioque. I've heard nothing but good things about their products and customer service. Their lowest amp is 249 and it's perfect for those subs. You'll get a warranty Also when you buy the amp.
